The Illinois Department of Revenue (IDOR) has issued an informational bulletin summarizing local sales tax rate changes that will take effect on July 1, 2026.
The bulletin, titled Sales Tax Rate Change Summary, Effective July 1, 2026, identifies certain taxing jurisdictions that have imposed a local sales tax or changed their local sales tax rate on general merchandise sales. According to IDOR, the affected locally imposed sales taxes include business district sales tax, county public safety tax, home rule municipal sales tax, Metro-East Mass Transit District sales tax and non-home-rule municipal sales tax.
The information is relevant for counties, municipalities, retailers, servicepersons and others responsible for collecting, administering or communicating local sales tax changes. County officials may wish to review the bulletin to determine whether any local rate changes affect their jurisdictions or unincorporated areas.
For county governments, the bulletin may be of particular interest to county administrators, treasurers, finance officers and other officials involved in local revenue administration, public notices, retailer communication and financial planning.
IDOR also provides an online Tax Rate Finder and machine-readable tax rate files that retailers, software providers and local governments can use to confirm applicable sales tax rates by location.
ISACo will continue to monitor state tax administration updates and share information relevant to county government operations.
